An overview of a sample configuration for the Arch Rock Energy Optimizer for data centers.

Cisco Systems has announced plans to acquire privately-held Arch Rock Corporation, which makes wireless monitoring systems used in data centers. Cisco says Arch Rock's technology will allow it to offer advanced monitoring systems for "smart grids" for the utility industry.

"Arch Rock’s wireless mesh technology enhances Cisco’s IP-based, end-to-end smart-grid offerings," said Laura Ipsen, senior vice president and general manager of Cisco’s Smart Grid business unit. "This acquisition further positions Cisco as a strategic partner to utilities working to better manage power supply and demand, improve the security and reliability of energy delivery, and optimize operational costs."

But the focus on utilities and smart grid applications appears to leave an uncertain future for Arch Rock's products for data center monitoring, which aren't mentioned in the release. Last year the company introduced a new version of its Energy Optimizer wireless monitoring system customized for data center monitoring. We followed up to inquire about Arch Rock's data center offerings.

"Cisco will continue to support existing customers that use Arch Rock’s data center products, and will look to evaluate the fit of the other innovations beyond Smart Grid that Arch Rock brings to Cisco’s existing technology areas," Cisco said in a statement.

Wireless monitoring is valuable in data centers because it allows company to retrofit existing data centers to detect “hot spots” where cooling may not be reaching servers. Fine-tuning cooling systems allows data centers to make more efficient use of the energy used for cooling, which often consumes nearly as much power as IT equipment.

When the acquisition closes later this year, the Arch Rock team will become part of Cisco’s industry-leading Smart Grid business unit. Financial terms of the transaction were not disclosed.
